Question about 1991 Chevrolet Silverado 2500
Ok.... 91 chevy 1500 pickup. When I turn the ac on the ac display flashes (never seen that before) and the compressor wont kick on. Freon is good, checked for voltage at the switch on the accumulator, no voltage. ran 12volts to the dark green wire on that switch, compressor kicks on ac is ice cold. where do we go from here. Any help is greatly appreciated.
Just had the same issue and posted. Just found the solution is the control module in the dash. Went to the junk yard since new is expensive on these units. Plugged new unit in, was able to charge a/c now blows cold as ice.
